BRIEF DESCRIPTION OF THE DRAWINGS
The system and method in accordance with the present invention are illustrated in this application by showing how a personal golf putter can be configured and how a system and a method of training a golf player can be carried out in accordance with the invention. Also, a system and a method of manufacturing a personal golf putters is disclosed, which is not a part of the present invention but can use the inventive golf putter. It is however to be understood that the term “golf putter” is used in a broad sense, and the same system and method can be used for manufacture of other personal clubs, such as drivers, irons, wedges, sand wedges and similar golf clubs.
As shown in
The means for sensing characteristics of the golf putter during swinging, the means for collecting and processing data corresponding to the sensed characteristics, and means for transmitting corresponding data to a computer are incorporated in the golf putter.
The output of the putter 300 is wirelessly connected to the computer 60. The computer which can be formed a pocket PC; IPAQ 5400 series HP-Compaq computer with built-in integrated display 62 for reviewing visual images and text messages.
In one exemplary embodiment of the present invention, the computer 60 can include software for interacting with the putter data and control signals.
At design center—swing data are analyzed using engineering workstations with software means to configure a specification for new putter head which is shown in
The putter system as disclosed contains an exemplary Putter 300 (
The switch 360 is used for turning on the electronic system of the golf putter (for example by pushing the switch and letting it go), for activating of sensing, data collecting and processing, and transmitting means (for example by further pushing the switch and letting it go), for resetting the electronic system in the event of malfunction (for example by pressing and holding the switch for 10 sec), for loading a new software into the microprocessor which collects and processes data and acts as a controller for controlling the system through the software (for example, by pressing and holding the switch for 30 sec).
The light emitting diode 366 in correspondence with the above-listed modes of the switch 366a, for example flashes for 15 sec, comes on and stays on for 2 sec and then turns off, flashes very quickly 15 cycles per 1 sec, flashes at 60 cycles per sec., correspondingly.
A speaker 366a (
A screw cap 367 is provided for closing a compartment for the battery.
The putter head 320 includes a hosel 310, a back surface 380, a heel 314 and toe 317, a sole 330, and a front strike face 325. The front strike face 325 is flat, and is set at approximately 4 degree loft 327 with respect to a line perpendicular to the sole 330. The putter head 320 and a putter shaft 304 are configured such that the putter 300 has a 74.degree.lie 390. The said lie angle, 390 can range from 60 to 85 degrees as a part of custom fitting.
In
Table I includes Z,X and Y axes data set as transmitted by the putter 300 of an actual swing.
The golfer 5 is equipped with the Putter 300 of known specifications which is an initial putter. As explained, putting results are used in custom fitting of a personal putter in accordance with the golfer's individual swing characteristics.
For example, it has been determined that, putter with strike face 325 has a 4.degree.loft to impart a perfect roll on the golf ball at impact enabling the golfer to better control ball direction of travel and the ball speed factor (
The system determines a particular golfer's 5 forward press tendency (see
In another example, the system determines a particular golfer's 5 rearward press tendency (see
In the event the data collected on a golfer shows such type of inherent natural behavior, as described above; (either forward press tendency,
Similarly, loss of energy and direction results in deviations resulting from the lie angles and open or close positions of the putter striking front face at impact. By analyzing the data, it is determined that the golfer 5 is slicing or drawing the golf ball at impact.
It is also determined if the golfer is keeping the club face square through impact or, alternatively, whether the golfer is opening or closing the club face through impact. This is combination of information available in the putter path 420
For a right handed golfer, “slicing” refers to those situations wherein the ball is imparted with a force resulting in clockwise spin rotation about the balls center axis, when viewed from the golfer's perspective, upon impact a sliced putt may result when the putting stroke starts outside the proper swing plane, and then proceeds to move towards the inside of the swing plane upon impact with golf ball B
In the computer the golfer's data are analyzed and golfer's preferred tendencies during the putting stroke are determined.
Depending on the desired means for storing data obtained from Putter 300, computer 60 may additionally be wirelessly connected to other peripheral devices such as video cassette recorder (VCR), a DVD player, or a CD RW ROM (read and write) drive. The computer 60 includes a software for converting digital data in meaningful images and text messages formed from data collected from the VisVia Putter as shown in
This is an efficient process and lends to having professional golf teachers and others in the field of golf to have the ability with the invented apparatus to collect data form golfers.
Additional details for determination of corresponding characteristics and calculations of corresponding data are presented herein below.
How to Measure Accelerations of Putter Head and Ball Speed Factor: (
MEMS accelerometers, manufactured by, for example, Analog Devices, Massachusetts company, model numbers ADXL 202, ADXL 210 (or other similar parts manufactured by other companies) can be used as liner acceleration or force measuring sensors for sensing the movement of the putter head. In this invention, Analog Devices parts, ADXL 210, 202, 260, and 183 were used.
There are two forces; one is gravity force which is a constant, and second force is the variable force which changes in the sensor mounted in the club head as the golf club moves. The changing variable force is monitored continually monitored with respect to the gravity force constant. Motion as influenced by gravity forces which for the invention is constant as all the motions are done on the earth's surface.
The sensor 340 assembly comprise a linear dual axis accelerometer sensor 340A and Gyro sensor 340G, positioned in the clubhead,
Table I, Z axis, column A is representative of the data collected for a putting stroke from this sensor 340A-Z This data, velocity-time graph is plotted, example of an actual swing is shown on
The data form the gyro sensor 340G is not displayed but it is similar to the 340A, and in this invention the Gyro sensor data is to measure angular rate of change of the putter head about the shaft 304 axis of rotation. In this invention, it is important to know the position of the putter face 325
Distance traveled by the putter head on the back stroke and forward stroke at any interval can be calculated from the velocity-time graph data base for the Z-axis (sensor 340AZ). From this data, acceleration factors are calculated; by definition, “a” acceleration is change in velocity over change in time.
Distance traveled over finite time 0.008 second interval as used in this invention is only an example, is calculated from the collected data obtained related to velocity over that time period. All calculated distances are summed up on the back stroke and like wise all forward moving putter stroke distances are calculated and summed.
This back stroke and forward stroke distance verses impulse force imparted to the golf ball at rest is one of the determining factor in putter weight measure in custom fitting of the golf club. It is a measure of how efficient a golfer is in putting, in controlling ball speed and direction, which translates into accuracy. Shorter strokes result in higher accuracy. Stroke distances create momentum, which directly corresponds to ball speed and distance it rolls on the putting surface. This however needs to be optimized, and this invention can assist golfers to do just that optimization process. Or golfers can train to develop sensitivities to distances and hands grip force applied to the putter.
Forces can be measured from the data base by using well known Newton's Law of Motion.
First law—has to do with mass of the putter head. Mass of a body is a measure of its inertia. For all practical purposes for the determining the cause and effect in golf, we will consider mass to be same as weight of the putter head, weight of the shaft and off course the total weight. Typically, putter weight ranges from 300 to 425 grams.
Second law—Force is equal to rate of change of momentum. The rate of change of momentum of a body is proportional to the resultant force applied and occurs in the direction of the force. The momentum of a putter head of constant mass “m” moving with velocity “v” by definition in physics is a product of the two, “mv”. (M=mv) And as this movement of the putter head is caused by a golfer applying the necessary force by holding on to the putter shaft at the grip location, therefore resulting in change of momentum, we can represent this as mv1 and mv2 and as this change is taking over a finite time change,: we can then calculate force. As Force is proportionate to the difference in momentum 1 and momentum 2 over time “t”.{F=mv2−mv1)/t}
Grip pressure applied at the moment of impact with the ball plays a very significant role on the impulse force imparted to the ball. Grip pressure analysis can be performed from the data and comments can be conveyed to the golfer via computer generated voice or text messages on the display interface.
If we make the time factor very small, for example one microsecond, for the application of golf and for this invention, Force impulse can be calculated—that is a very short duration force applied to an object, like a golf ball at rest. When the said golf ball B is hit with putter head 320
The well known laws of conservation of momentum is applied in this invention. And knowing the mass of the golf ball and the mass of the putter head, one can calculate the rest state( zero velocity V=0) to instantaneous velocity Vi of the golf ball when hit. This is the ball speed factor calculation. (MpVp=MgVg), Mp is Putter head mass, Vp is Putter head velocity and Mg is golf ball mass, and Vg is golf-ball instantaneous velocity. Mass is equal to weight for all calculations for this invention.
Kinetic Energy is the energy putter head has because it has motion, or is in motion during the forward putting stroke, Kinetic energy, Ek, of a putter moving at velocity v; is equal to ½ Mv2. Kenetic energy is another methodology for calculating ball speed factor.
Consistent grip pressure is necessary to impart consistent force to the golf ball at rest assuming other factors such acceleration and putter weight being constant and consistent. Impulse Force measure to gather with club head velocity and putter weight can provide feedback on the grip pressure.
How to Measure of Lie and Loft and Angles
MEMS accelerometers ADXL 320 and ADXL 322, parts manufactured by Analog Devices, part no ADXL202 and ADXL 210 and other similar parts manufactured by other companies in the trade is used in this invention to take advantage of the gravity as an input vector to determine the position of the golf club-grip in free space. As the golf grip is part of the shaft, which is rigid and which is connected to the putter head, by measuring the position of the grip in free space the putter face position with respect to the vertical plane is determined with good resolution and repeatability, which conveniently happens to be the same as gravity vector. This applies for both the loft and lie angles.
In our golf application,
Hence in the putter, the dual axis sensor' both sensitive axis is positioned in the putter handle, so that the sensor's sensitive axis are perpendicular to the earth's gravity vector. And since the X and Y axis of the sensor are orthogonal to each other by position the sensor in the handle so the X axis is oriented to measure the lie and angles and the Y axis is positioned to measure the loft angles
The data is used in mathematical calculations where the “mg” (milli g) experienced by the sensors are converted in to electrical signals which in turn are used to determine the tilt angle. This information is then displayed on the display of the computer.
How to Measure or Determine the Putter Path?
Determination of the Putter path 420 is performed by use of X and Y tilt angles over time base form the sensors 350A in the putter shaft, 304 and the position of the putter head as measured by sensor 340 as per distance traveled in the putter head 320 also over the same time base. These three points over time base provides the means to determine mathematically the exact position of the putter head along the forward and backward stroke of the putter head in the line of the putter path and its lie and loft angles at any given time during the putting stroke.
Sample Calculations for Measure of Lie or Loft Angles:
Sensor 350A is positioned in the shaft and it sensitive axis X and Y is perpendicular to the earth's gravity vector.
At 0 g=90 degrees grip handle position 96
The circumference of the grip travel with putter sole 97 as a pivot point is simply 2pieR, pie=3.174, R=36 inches. And since, we are only concerned over 90 degree angular travel, the quarter circumference, pie/2×36=57.132 inches. This comes to 0.6348 inches per degree change in the grip handle position. Per analog Devices specification the sensor out put as per inventions positioning in the shaft, results in 17.5 mg out put per degree change. The system design per invention is able to measure 0.1 degree resolution with good repeatability.
The important feature of the present invention is that the sensing means, the data collecting and processing means, and the data transmitting means are incorporated in the initial putter. How these means are mounted on and connected to the initial putter is not Germaine to the invention, and conventional techniques are possible.
The sensor assembly can be mounted inside the putter positioned just below the hosel 310. The assembly is inserted from the bottom side (sole 330) of the putter end and sealed with RTV and epoxies with a thin metal plate for fine finish.
In accordance with the present invention it is possible to provide a system and a method of training golf players in a new and more efficient way.
In addition to training, the invention keeps score of your swings, and several swings collectively analyzed results in monitoring the golfer effectiveness on hole by hole bases, game by game bases the overall golf game. This analysis is performance evaluation with respect to lowering golfer's score, golfer's handicap as is generally known—numbers of strokes over 18 hole-game, is averaged and a handicap is assigned to each player. It is measure of how good a player one is. Golfers can have handicaps ranging from zero to 30. The goal is to lower that number to zero. That is a scratch player-tour player are in the zero category.
The main objective or the goal for the golfer is to train to get better in putting. This comprises of two factors—Stroke mechanics and the ability to read the greens. The invention is concerned with attributes or variables released to Stroke mechanics—putter head acceleration and deceleration, putter face angles, putter path back stroke and forward stroke, swing tempo (time factor in a swing) and custom club fitting).
All these variables taken together, they collectively contribute to golf ball's speed-rolling of golf ball (distance per time, e.g. feet per seconds) and direction. The direction is usually measured with reference to the position of the golfer and the hole. Is the ball traveling to the right or to the left of the hole or is it centered on the aim-line-in the hole. This is with respect to the golfer's vintage facing the hole from where he is, where the ball is.
The most important and really what matters is the ability to stroke the ball so that the ball will roll into the hole with minimum number of strokes per round of golf, that is 18 holes play, or at times 9 holes play. And to do this, golfer needs to have ball speed control and ability to roll the ball along the chose aim-line. Aim line is the path the ball should roll on to the hole. If the ball is stroked to hard (high force)—meaning with high putter head velocity (force=putter head mass time velocity), and assume it is on aim-line, the ball may just go over the hole and will come to rest way too far from the hole. The objective is to stroke the ball at a controlled putter head velocity and face angles to so the ball will begin to roll along the aim-line with just right velocity to reach the center of the hole, or some desired objective.
In accordance with the present invention Putter Head acceleration and deceleration are measured and instantly displayed—on the color coded acceleration bar—the green represents putter head is acceleration towards the ball, red shows it decelerating, and black is constant speed. The objective is to ensure it is all green. That is a sign of a good putting stroke. —This shows golfer is gripping the putter with just right pressure. If it too tight-muscle tension causes acceleration and deceleration and can be seen the bar graph. It also shows the swing is smooth with constant acceleration force applied to the putter head.
Further putter head face angles are measured and instantly displayed—he and loft angles at address and at ball hit. The interface display shows the red circle, it represents top of the putter grip position with respect to the ball. This red circle should always be on target—that is the reference circle—brown color representing the ball on the green or on the floor. So golfer need to practice to always have the red ball on the target brown circle. Similarly, the Blue circle, position of the putter grip top needs to be in either on the top of the reference brown circle. The blue represents the position of the grip-hands at the moment of the ball hit. This should be consistent from stroke to stroke to provide with a measure of distance control and ball direction. The individual golfer's reference is established in degrees, it is an average of several swings taken under controlled observation by a teaching professional and the goal is to be at the reference for stroke to stroke during practice.
Further Forward Stroke Distance is measured and displayed in inches or mm or centimeters. This measure is to enable golfer to practice against a predetermined objective. For example-lesson one, practice 5 inches putting stroke. The golfer putts and determines how well that distance objective can be reached. The distance objectives or goals can be varied or constant.
Further Forward Swing Tempo is measured and displayed—time for the swing or the putting stroke measure. This is part of the golfer's mental signature; this time element should be consistent. Golfer should pay attention to this data and strive to be within 5% of the individual's norm.
Further Ball Speed factor is measured and displayed. —This measure is to enable golfer to practice against a predetermined objective and for given conditions. For exaple the given or set condition can be Stimpmeter rating, e.g. 10.5 is set condition. For example—lesson one, practice putting strokes resulting in 10-feet-putts or for example 12-feet-putts. The golfer putts and determines how well that distance objective can be reached. The distance objectives or goals can be varied or constant. The measure of improvement is function of well the golfer is able to control ball speed against predetermined values. This is directly connected with the muscle memory development that can be effectively learned from instant feedback the invention provides. Ball speed factor is determined from collective data base of putter head velocity, putter head impulse factor and face angles.
Further Putter Path is measured and displayed—the yellow line—putter head path forward stroke and the redline putter head path back stroke shows how stable the golfer's swing is. This has to do with correct grip, grip pressure, pendulum type of swing or not. The objective is having a straight line back and forth for a good stroke. This is most preferred method and most effective putting method.
Putter head velocity is measured and displayed, inches per second. This measure is to enable golfer to practice against a predetermined objective. For example—lesson one, practice putting stroke with putter head velocity of 35 in/sec at ball hit. The golfer putts and determines how well that velocity objective can be reached.
The invention can be used to play golf game with On-line Golf Game on line indoors or out doors. The variables measured as discussed above are collectively used to determine if the putting stroke resulted in golf ball rolling into the hole or if it missed due to poor stroke. As such the rules of regular golf game are applied to the on-line golf game played using this invention. An individual golf player can play the on-line golf game alone, or compete with other golf player/s. the invention replaces the conventional joysticks as used by on-line video golf games. It uses the real golf product that works wirelessly connected to remote terminals commercially available from Microsoft and Sony.
It will be understood that each of the elements described above, or two or more together, may also find useful application in other types of methods and constructions differing from the types described above.
While the invention has been illustrated and described as embodied in a golf putter for, system and method of training a golf player, it equally applies to driver and iron clubs, and it is not intended to be limited to the details shown, since various modifications and structural changes may be made with out departing in any way from the sprit of the present invention.
Without further analysis, the forging will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, form the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
